Title: Blind hollow riser for foundry sand mould - has double wall forming ring gap entered by molten metal to retard cooling of metal inside riser
Inventor: BAUR EDUARD DR ING
IPC: B22C9/08
Filed: 1979-07-12
Abstract: Parent patent described risers or feeder heads made of refractory material and embedded in sand moulds. In this addn. the riser has a double wall (11,15) sepd. by a ring gap (16). The two walls (11,15) pref. have the same height; and the inner wall pref. has slots via which gap (16) can be filled with molten metal. The base of the riser is pref. closed by a ring core forming a ring notch in the metal solidifying in the riser to form a head; the notch permits the head to be knocked off the casting without difficulty. The riser cavity filled with molten metal is surrounded by an outer gap (16) which is also filled with molten metal, so cooling in the actual riser is very slow. Very efficient feeding of the casting during its solidification is ensured.

Patent DE-2941903-A1 (DE)
Title: Carpet tufting process with versatile patterning capability - uses hollow needle to draw individual tuft lengths through backing
Inventor: SCHOLZ HARTMUT
IPC: D05C15/00
Filed: 1979-10-17
Abstract: A process for the production of tufted carpeting, and a machine for performing the process, uses a hollow needle which penetrates a backing fabric from the underside. One of a selection of pile yarns of different types or colours is presented to the needle, is drawn inside by suction or by a mechanical gripper, and is drawn through the backing as the needle withdraws. The yarn is severed at the required pile height; relative movement occurs between backing and needle, and the needle penetrates the backing anew, taking with it the end of the new tuft, which pulls out of the needle as it advances.. The needle function is limited to that of looping the tuft through the backing, and specialised mechanisms are provided to deal with yarn selection and transport. This eliminates the patterning limitations of previous tufting processes. The action of the needle protects the yarn from damage as it is drawn through the backing fabric.

Title: Control system regulating speed of drive roller - enables speed of roller in rotary printing press to be equalised with paper-web speed
Inventor: SATERINI MARIO
IPC: B65H23/192
Filed: 1980-06-02
Abstract: The control system measures the tension in the paper web being moved by the roller. A signal representing this tension from an electrodynamometer (16) is compared with a reference in a first comparator. A second comparator compares the peripheral speed of the roller with the feed speed of the paper web. A third comparator compares the outputs of the first and second comparators to produce a signal that controls the speed of the drive roller. The tension in the web is thereby controlled continuously and slip between roller and web avoided along with the disadvantages (e.g. smudging of print) associated with such slip.

Patent DE-3117927-A1 (DE)
Title: Arrangement for identifying the longest of strings of zero characters cyclically contained in digital signals
Inventor: DOEMER JOSEF ING GRAD
IPC: H04B17/40
Filed: 1981-05-06
Abstract: It is known for devices transmitting digital signals to be controlled by means of strings of zero characters or one character which are inserted in the digital signals. In the case of remotely powered devices with high transmission speeds, difficulties arise since the high-speed identification circuits normally implemented by means of pulse counters require a substantial proportion of the remote-feed current and because the spectral component of the string which is to be identified may be small compared with the transmission signal. According to the invention, the digital signals are converted into unipolar binary signals which control a switch which, for the duration of the positive signal pulses charges a first integrator which discharges for the duration of the zero character string. A second controlled switch with an integrator can be connected downstream to improve the identification. The invention is used in particular to identify the loop closure command in transmission paths for high-bit-rate digital signals. <IMAGE>
